I like this dimmer a lot. It dims from fully on to completely off and everything in between (obviously) You can build one of these for yourself and I have done that in the past but I paid more for parts (or at least as much) as I did for this. Bottom line, if you want a dimmer for cheap then this is your product.

As a lighting technician for more than ten years I have worked every dimmer under the sun. Now while this dimmer is not perfect, it is the best dimmer you can get at this price. The PROS: Works well with any-any incandescent fixture 1000W or less. It also feels well built and looks relatively attractive. CONS this dimmer is not totally silent. IF you need something that wont hum at all I would not buy this but the truth is any dimmer that is this size and near this price point will hum so as long as you are expecting this I don't think it is a negative thing. Overall impact has done a great job in offering a good dimmer at a good value. I would recommend this.

Have been using this with a 150W bulb and I love every minute. The dimmer is just all around well made. I like the length of the power cord and there is no buzzing or any other sound. Additionally, the slider feels well made and slides smoothly. I can now adjust the light while a movie is playing and then make it brighter when people need to get up with out tripping over their own feet or, more awkwardly, someone elses.

Fantastic product!!!!!!!

Works as it should! This is a really great portable dimmer easy to carry and dims all the way down. I have worked with lots of different dimmers and even made some of my own from parts. I couldn't believe this one was even cheaper than the parts I use when I make my own and still works well! great value - can't go wrong at this price! The only complaint I have heard people have is the slight humming noise but every dimmer does that without a variac and that adds so much weight I much prefer a lightweight one unless I need it to be absolutely silent. I give this product five stars.

I needed to dim my backlights and practicals so the other day I finally got around to picking this up from istockonline. It is good and sturdy and very practical As an added plus it will save your bulbs from using too much wattage so it will also extend their lives.

If I had to give the two most important ingredients for shooting video I would say they are audio and lighting. This is why I love the dimmer so much. However much I liked my setup before, I now have this useful gadget to make the lighting exactly perfect. No more changing bulbs, or screaming "more diffuser, no less diffuser, I have no idea what to do now etc..!!! This is a nifty product that deserves a place in everyone's bag of tricks.

I like this dimmer. I use it with my u-lite system and I have found it very convenient. The dimmer makes no sound and the slider is well built. The cord could be a bit longer but i'm not complaining.

I cant believe I ever bought a pricier dimmer. This works with all of my light kits and works well. At this price I expected some issues but this dimmer is perfect. I highly recommend.

Wonderful dimmer for up to a 1K. I am only not giving it five stars because of two things I didn't love.

1) There is no on and off switch. It would be better if I can slide it half way and then turn it off so that when I turn it on again it will be set where I want it.

2) Another small problem is the sound. Even when the slider is all the way off it creates a thin sound that only goes away if you actually turn the light off.

THis is how every dimmer is unless you get a 1K variac but they cost a hella lot more so all things considered I am happy with this purchase.
